This was a fun build as it tested alot of my skills especially on how to use the grey pieces of which I am totally new to.
I thought about the initial idea that I wanted the defining feature to be that it had to have alot of the skulls on and around it. I started out with one of my favourite parts of this moc, the feet which came out quite well. The head was the last thing to be made and in-case your wondering, the two ball joints on the underside of the piraka skulls are meant to be the eyes.

Very well may be the most intelligent use of those skulls I've ever seen. Dunno why I didn't use them as toes - I've got enough white MOCs... makes me wanna re-design FrostHulke's feet...hmmmm. Cheers on the hulking fellow!

Reminds me of when I used to make many grey mocs for contest entries. this is really monstrous and filled up with loads of pieces. I'm actually gonna say this is probably you best moc, and if not, it is my favorite ! Really awesome job, and great humanoid look to a bull ! Even with the pistons and those awesome big feet, i'm still surprised he can stand. Bravo, this is amazing :D

Very cool. Well built and colorus work. I really lik the head, but I think lges could be bulked up quite a bit. Also, not sure about the hands, they don't flow very nice with the arm. But yeah, its very nice.

I know, It's mainly the upper leg part (between the thigh and knee) that could do with work. The hands were hard to figure out and I know they look a bit wierd and I'm not so good at larger mocs but I still count this as a success :)
